GSAT–7A is a communication satellite scheduled to be launched from Satish Dhawan Space Centre, Sriharikkotta on December 19, 2018. Here are some facts about the mission and the launch:
- The advanced military communication satellite GSAT-7A is the 35th Indian Communication Satellite.
- GSAT-7A will be the first satellite built primarily for the Indian Air Force to interlink, operate and communicate with its aircraft as they fly and with command centres on ground.
- The Satellite will be launched by GSLV-F11 from the second launch pad of Satish Dhawan Space Centre in Sriharikota on December 19. This will be the eight launch of ISRO this year. The GSAT 7A satellite Using Ku band frequency will enable superior real time aircraft-to-aircraft communication; and between planes that are in flight and their commanders on the ground.
- It has a planned mission duration of 8 years.
- The Satellite is built to provide communication capability to the users in Ku-band over the Indian region.
- About 70% of GSAT 7A services would be for the Air Force and the rest for the needs of the Indian Army. Army Aviation Corps, the aviation arm of Indian Army, operates many helicopters, uses UAVs and will acquire fixed wing aircraft in future — all for surveillance and rescue missions. They can also make use of facilities provide by this satellite.
- GSAT–7 which was launched in August 2012 helps the Indian Navy to link its ships to command on land.
- This will be the last mission of ISRO in 2018. The other missions of ISRO in 2018 are given below:
GEOSYNCHRONOUS SATELLITE LAUNCHING VEHICLE (GSLV) – F11
- This will be the 13th flight of Geosynchronous Satellite Launching Vehicle (GSLV)
- The GSLV-F11 is the seventh flight with Indigenous Cryogenic stage, will place the 2,250-kg GSAT-7A communication satellite into a Geosynchronous Transfer Orbit.
- The satellite will be placed in its final Geostationary Orbit (GEO) using the onboard propulsion system.
- GSLV – F11 is ISRO’s fourth generation launch vehicle with three stages. The four liquid strap-ons and a solid rocket motor at the core form the first stage. The second stage is equipped with high thrust engine using liquid fuel. The Cryogenic Upper Stage forms the third and final stage of the vehicle.
